Graph

These algorithms provide generic graph coloring capabilities used by Gauss-Seidel, multigrid aggregation, etc... We distinguish to main categories of algorithms, distance 1 coloring and distance 2 coloring. We also provide a coloring handle that allows users to easily control the behavior of the algorithms.

Graph coloring handle

The graph coloring handle is extending the KokkosKernels handle to provide options that are specific to coloring algorithms.

Distance 1 graph coloring

Distance 1 coloring algorithms will ensure that each node has a different color than all of its neighbors.

• Graph Coloring

Distance 2 and One-sided Bipartite graph coloring

Distance 2 coloring algorithms will ensure that each node has a different color than its neighbors and its neighbors' neighbors.

• Distance-2 Graph Coloring
